Figure 6: Box plot showing the medians and distributions of difference in buccal and lingual alveolar wall (–) and total bone thickness (, ) in comparison to equivalent measurement on the corresponding mesial root of each defect site 1 mm (), 3 mm (), and 5 mm () apical of the buccal and lingual bone crest (). The whiskers of the plot represent the 5th and 95th percentiles, *statistically significant difference in this parameter (), .
